Unable to install Mac OS Catalina Update 10.15.3 on my MacBook Air
I have been trying to update my MacBook Air with 10.15.3 update. When I select "Update now", it says "Restart required".....
And when I restart, it simply pauses for a second to install the update, then skips the installation and restarts.
How do I update my Mac ?
Thanks for your help in advance.
MacBook Air 13", macOS 10.15
